    I might have found a really strange bug in the Calculator (OS X 10.2.2)--the paper tape seems to have rounding issues. I wonder if it's just my machine--I sent the bug report below to Apple in any case:

    I found a strange bug in the calculator (OS X 10.2.2) where the paper tape shows a different result than the regular display. To reproduce:

    * Start the Calculator, and click the "Paper Tape" button to show the paper tape.
    * Then type 1028 - 350 + 16.93 and hit the equals key
    * The display shows "694.93" as it should, but the paper tape shows this:

    11/30/02
    3:28:39 PM
    ------------
    1028 -
    350 +
    16.93 =
    694.9299999999999 ◊

    It's kind of funny, but makes me hesitant to trust the Calculator....

    Minor rounding oddities have been present with computers for years, if not decades. They're a pain, but understanding that they arise due to binary/decimal conversion oddities "helps" make them something to be casually observed rather than being frightening (IMHO).
